1 Claim.

' structed for directing offensive odor from the bowl, and which isdrawn therefrom by suction means that exhausts the same exteriorly ofthe building through suitable vent means.

A further object is to provide a toilet bowl seat that has a chambertherein, in the form of a conduit along the length thereof, as well asinlet openings extending from the bottom of the seat to the chamber andthe latter communicates with suction means through the medium of thehinge for the seat.

Another object is to provide a ventilating apparatus of the characterset forth, that is simple in construction, inexpensive to manufacture,and extremely efficient in operation, use and service.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure l is a top plan view of the apparatus, with parts broken away andin section.

Figure 2 is a side elevation thereof with parts 35 broken away and insection.

Figure 3 is a sectional view taken approximately on line 33 of Figure 1.

Figure 4 is a sectional view taken approximately on line d-t of Figure1.

Figure 5 is a sectional view taken approximately on line 5-5 of Figure1.

Figure 6 is a fragmentary bottom plan view illustrating the doubleT-coupling between the seat chamber and the hinge. 45 Referring to thedrawing in detail, the letter A indicates a toilet bowl of the usualconstruction having a rearwardly directed hinge mounting extension B andwhich is shown to illustrate the application of my seat and the hingethereto. 50 The seat in the form shown is of the open front type andpreferably includes upper and lower sections I and 2, each having agroove in the inner fiat face thereof, so that when the sections aresecured together in face to face relation by screws 3 or the like thegrooves provide a chamber 4 that extends from adjacent the forward endsof the seat along the remaining portion thereof, as clearly shown indotted lines in Figure l. The sections may be made from any materialsuitable for the purpose, but I preferably make the lower section fromCelluloid or the like and the lower section is provided with a pluralityof holes 5 extending through the under face thereof and communicatingwith the chamber, as best shown in Fig-.

ure 5, the holes providing inlets, as will be apparent, and they mayhave beveled outer ends.

The rear portion of the seat is slightly enlarged as at 6 and hasmounted therein to extend centrally from the rear end thereof, thehollow shank l and one head 8 of a double headed T- coupling il. Thehead 8 is disposed to communicate with the chamber 4 and fixedly mountedin the other head of the T-coupling to extend outwardly therefrom arealigned pipe sections It and II that have mounted thereon the collars l2of hinge members I3, the latter being fixed to the underside of the rearportion of the seat by screws, as clearly shown in Figure 6. The head 8is likewise provided with a hole as clearly 25 shown in Figure 6.

The extension B is provided with a pair of openings and disposed throughone of the openlugs and secured accordingly is the shank H of a ballheaded member 15 having a recess extend- 3% ing laterally therein from acollar I6 that has the solid outer end portion of the pipe section Illpivotally mounted therein, while the other pipe section II is pivotallymounted in a collar ll formed on a hollow ball headed member I8 whichhas its hollow shank l9 extending through and secured in the otheropening of the extension 13 as best shown in Figure 3. The end of thepipe section Ii that is mounted in the collar ii is beveled as at 20 forfitting a beveled seat therein and is held seated, by a coil spring 2!engaging the inner end of the recess of the member l5 and the solid endof the pipe section Ill, so that a tight joint will be provided betweenthe member l8 and the pipe section H, to prevent leakage of airtherefrom, as will be apparent.

A suction fan 22 is included in my apparatus and it is shown as beinghoused within a casing 23 mounted within a partition or wall C, -.but of59 course it will be understood that the fan can be disposed at anyappropriate place, providing the outlet or exhaust pipe 24 communicateswith a suitable vent opening or extends exteriorly ofthe building. Thewall shown is an outer wall of the building, with the exhaust pipeextending exteriorly thereof.

Connected to the lower end of the hollow shank I 9 by a nut coupling, inthe form shown, is one end 01' a pipe 25 that has its opposite endconnected to the tan housing as clearly shown in Figures 1 and 2. Themotor of the fan is controlled by a switch 20 secured to a lateralextension formed on the ball headed member l8 and the conductors for theswitch extend through the member l8, the shank l9 and the pipe 25, withthe result it will be seen that they are completely housed. as will beapparent upon inspection Figure 3.

From the above description and disclosure in the drawing, it is believedthat the operation of my apparatus will be obvious, but it might bementioned that upon closing the circuit to the motor of the fan, by theswitch 28 that is conveniently arranged, as best shown inFlgure 2, thefan will draw air through the inlet holes I, and consequently ofl'ensiveodors from the bowl, the air and odors thence being directed to the fanhousing and finally to the atmosphere through the medium of the exhaustpipe 24.

It is thought from the foregoing description I h I" ing means.

It is to be understood that changes that the advantages andnovelieatures of invention will be readily apparent. .v
